Mechanical interlock mechanism of high-voltage segregate switch with vacuum contactor and high-pressure chamber cabinet door

高压隔离开关与真空接触器、高压室柜门的机械联锁机构

Abstract

一种高压隔离开关与真空接触器、高压室柜门的机械联锁机构,属于高压成套电气设备的安全保护装置技术领域。包括一安装于高压室的柜门的内壁上的第一机械锁定装置和一安装于所述的柜门的外壁上的第二机械锁定装置以及一用于操控所述的第一、第二机械锁定装置锁定或开启的钥匙,所述的第一机械锁定装置的位置处于柜门的门沿处。优点:整体结构简单,可靠性程度高;仅需在柜门上开设第一锁芯程度的安装孔,因此安装方便;第一、第二机械锁装置的成本仅为已有技术装置的十分之一,因此具有经济性;第一、第二机械锁定装置共同地受控于同一把钥匙,即两装置合用同一把钥匙,因此安全可靠。
The invention discloses a mechanical interlock mechanism for a high-voltage isolating switch, a vacuum contactor and a hyperbaric cabinet door, belonging to the high-voltage whole-set electrical device safety protective device technical field. The invention comprises a first mechanical lockup device arranged on the inner wall of the door of the hyperbaric cabinet, a second mechanical lockup device arranged on the outer wall of the door of the hyperbaric cabinet, and a key for locking or unlocking the first mechanical lockup device and the second mechanical lockup device; the first mechanical lockup device is arranged at the edge of the door of the hyperbaric cabinet. The invention has the advantages of simple structure, high reliability; and only a mounting hole for the bolt of the first mechanical lockup device is arranged on the door, so the invention is of convenient installation; the cost of the first mechanical lockup device and the second mechanical lockup device is just one-tenth of the prior device, so the invention is of good economy; the first lockup device and the second mechanical lockup device are both controlled by the same key, that is, the first lockup device and the second lockup device use a common key, so the invention is of safety and reliability.
